Patent number: 8314372Abstract: A heating roller performs electromagnetic induction heating, and includes a first exciting coil that heats the heating roller, a first degaussing coil that decreases magnetic fields of the first exciting coil, and a first axial direction core that guides magnetic fluxes, to make up a magnetic circuit between the first axial direction core and the heating roller. The width of a heat zone is controlled in agreement with a sheet feeding area. Thus, the capability to control a temperature increase in a non-sheet-feeding area of the heating roller is enhanced. Power can be saved during continual feeding of small recording sheets.Type: GrantFiled: March 24, 2010Date of Patent: November 20, 2012Assignee: Panasonic CorporationInventors: Masaya Yoshihara, Yasuhiro Torigoe, Fumihiro Tateno, Youichi Nakamura

Patent number: 7486923Abstract: A heat generating roller, fixing equipment and an image forming apparatus in which warm-up time is shortened while preventing excessive temperature rise and good fixing performance is realized by preventing offset. The heat generating roller is formed principally by laying a high permeability conductive layer and a nonmagnetic conductive layer in layer. When a voltage is applied from a power supply to an exciting coil and an alternating current flow, magnetic flux is generated around the exciting coil and a magnetic field is formed. Magnetic coupling of a system including the heat generating roller and the exciting coil is advantageous at a low temperature and heat generation of the heat generating roller is accelerated. When the Curie point is exceeded, skin depth increases and skin resistance decreases, which suppresses generation of Joules heat and reduces heat generation of the heat generating roller.Type: GrantFiled: July 26, 2005Date of Patent: February 3, 2009Assignee: Panasonic CorporationInventors: Masaru Imai, Noboru Katakabe, Youichi Nakamura, Naoto Matsuo, Tomoyuki Noguchi

Publication number: 20080063445Abstract: A heat generating roller, fixing equipment and an image forming apparatus in which warm-up time is shortened while preventing excessive temperature rise and good fixing performance is realized by preventing occurrence of offset. In the heat generating roller, fixing equipment and image forming apparatus, the heat generating roller is formed principally by laying a high permeability conductive layer and a nonmagnetic conductive layer in layer. When a voltage is applied from a power supply (not shown) to an exciting coil and an AC current flow through it, magnetic flux is generated around the exciting coil and a magnetic field is formed. Since the heat generating roller has the high permeability conductive layer and the nonmagnetic conductive layer laid in layer, magnetic coupling of a system consisting of the heat generating roller and the exciting coil is good at the time of low temperature and heat generation of the heat generating roller is accelerated.Type: ApplicationFiled: July 25, 2005Publication date: March 13, 2008Applicant: MATSUSHITA ELECTRIC INDUSTRIAL CO., LTD.Inventors: Masaru Imai, Noboru Katakabe, Youichi Nakamura, Naoto Matsuo, Tomoyuki Noguchi
